Type MG Precision High Voltage Resistors
Page 1 of 2
Now with Extended Resistance Range to 10,000 Megohms and Additional Models
Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.
Caddock's Micronox® resistance films are the source of
the Type MG Precision High Voltage Resistors' outstanding
combination of performance features:
Preconditioning for Power and Voltage Ratings
All power ratings and maximum operating voltage ratings
are for continuous duty. These ratings are based on pre-
stress voltage levels applied during the manufacturing
process to provide for stable resistor performance even
under momentary overload conditions.
Maximum operating voltages 60% higher than the values
listed in the table may be specified by adding "-15" to the
model number (Example: MG750-15). Note that overload
and overvoltage ratings do not apply to the "-15" resistors.
Resistance ranges for "-15" resistors shown in the table are
from "-15 Min." to "Standard Max."
• Single-resistor values as high as 10,000 Megohms.
• Maximum continuous operating voltages as high as
48,000 volts ("-15" ratings).
• Overvoltage capabilities of 150% of standard working
voltages for all models and values, (except "-15" ratings).
• Resistance Tolerances from ±1.0% to ±0.1%.
• Temperature Coefficient, for standard resistance range, of
80 ppm/°C in combination with resistance tolerances as
tight as ±0.1%.
• Type MG resistors have demonstrated stability of 0.01%
per 1,000 hours in extended load life testing of standard
resistance range values.
This exceptional performance has been proven through
many years of use in equipment that demands the highest
reliability and stability, including TWT amplifiers, X-ray
systems, geophysical instruments, and medical electronics.
Non-Inductive Performance
Most models are manufactured with Caddock's
Non-Inductive Design which uses a serpentine resistive
pattern that provides for neighboring lines to carry current in
opposite directions, thereby achieving maximum cancellation
of flux fields over the entire length of the resistor. This
efficient non-inductive construction is accomplished without
derating of any performance advantages.
